Abstract: A control apparatus for an internal combustion engine that is capable of switching between compression ignition combustion and spark ignition combustion is provided. The control apparatus is configured to perform fuel cut. The spark ignition combustion is performed over a time period after the fuel cut. The compression ignition combustion is permitted when the time period elapses. Fuel cut decreases the temperature within the combustion chamber. According to the invention, if fuel cut is performed, the temperature within the combustion chamber is raised by the spark ignition combustion. Since the compression ignition combustion is permitted after the temperature within the combustion chamber rises, engine misfire and an increase of NOx emission are prevented. The time period is preferably determined based on the temperature within the combustion chamber immediately before the fuel cut is performed.

Abstract: The present invention aims at expanding an operation range for allowing a compression ignition combustion operation. The present invention provides an internal combustion engine of a compression ignition type that is capable of operating with a compression ignition combustion scheme in a given operation range. The ECU of the internal combustion engine detects an operating condition of the internal combustion engine and determines, according to the detected operating condition, which mode is to be used operate the internal combustion engine, a 4-cycle compression ignition mode or a 2-cycle compression ignition mode. The ECU controls the internal compression engine to perform the compression ignition mode determined.

Abstract: A controller for an internal combustion engine capable of performing a compression ignition operation. The internal combustion engine includes a combustion chamber, and a fuel injector for injecting fuel directly in the combustion chamber. The controller includes: an air pressure detecting unit configured to detect at least one of an air pressure and an exhaust air pressure; and a fuel injection control unit configured to actuate the fuel injector to control a fuel injection timing according to a detected result by the air pressure detecting unit. The fuel injection control unit puts the fuel injection timing forward as the detected result by the air pressure detecting unit is lowered.

Abstract: In a chip-size package, an insulator tape is formed with a conductive wire having a wider section which is greater in width than other sections of the wire and a conductive bump connected to the wider section of the wire. The insulator tape is further formed with a first plurality of slits arranged on one side of the wider section of the wire and a second plurality of slits arranged on the other side of the wider section. An integrated circuit chip is provided having a conductive pad connected to the copper bump.
